When the powder material weighed by the weighing device body 9 reaches the specified amount, the through slot 5 can be immediately closed by the feeding assembly 6, and then the push plate 8 can be driven to move by the telescopic end of the first electric push rod 7, so that the weighed powder material can be discharged. In addition, by providing the stirring assembly 4, the powder material inside the storage box 3 is stirred, which can prevent the powder material inside the storage box 3 from agglomerating, thereby effectively ensuring the smoothness of the feeding of the powder material;

[0023] In this embodiment, the feeding assembly 6 includes a second electric push rod 601, which is fixedly installed on the inner top of the casing 1. One end of the telescopic end of the second electric push rod 601 is fixedly connected to a connecting piece 602, and one end of the connecting piece 602 is fixedly connected to a baffle 603. The baffle 603 is arranged inside the through slot 5. The telescopic end of the second electric push rod 601 can drive the connecting piece 602 to move, thereby driving the baffle 603 to move, thereby achieving the effect of opening and closing the through slot 5, and controlling the discharge amount of the powder material inside the storage box 3. When the powder material weighed by the weighing device body 9 reaches a specified amount, the baffle 603 can be driven by the second electric push rod 601 to close the through slot 5;

[0024] Furthermore, a clearance groove 10 adapted to the baffle 603 is provided on the inner top of the through slot 5. The baffle 603 is slidably inserted into the interior of the clearance groove 10. By providing the clearance groove 10, when the baffle 603 moves upward, it can be inserted into the interior of the clearance groove 10, which can facilitate the opening of the through slot 5.

[0025] Furthermore, a chute 11 adapted to the connecting member 602 is provided on one side wall of the storage box 3. The connecting member 602 is slidably connected to the chute 11. By providing the chute 11, the connecting member 602 is limited, making its movement process more stable.

[0026] In this embodiment, the stirring assembly 4 includes a rotating rod 401, the top end of the rotating rod 401 is rotatably mounted on the inner top of the storage box 3, the top end of the rotating rod 401 passes through the storage box 3 and is connected to a driving motor 402, and a stirring blade 403 is fixedly connected to the outer wall of the rotating rod 401, and the output shaft of the driving motor 402 can drive the rotating rod 401 to rotate, thereby driving the stirring blade 403 to rotate, and then stirring the powder material inside the storage box 3, thereby preventing the powder material inside the storage box 3 from agglomerating, thereby effectively ensuring the feeding smoothness of the powder material;

[0027] It is worth mentioning that the drive motor 402 is fixedly installed on the top of the storage box 3, and one end of the output shaft of the drive motor 402 is fixedly connected to the top of the rotating rod 401. The drive motor 402 is configured as a stepper motor. The stepper motor can accurately control the rotation angle and frequency, which makes the operation of the stirring component 4 in the storage box 3 very precise. This precise operation control helps to ensure that the powder material is evenly and fully mixed during the stirring process, thereby effectively preventing the occurrence of agglomeration. The stepper motor has excellent stability and reliability and can maintain stable performance in a long-term, continuous working environment. This means that the stirring component 4 can work continuously and stably, and the stirring effect of the powder material will not be affected by fluctuations or failures of the motor. This stability is crucial for powder weighing machines that need to run for a long time;

[0028] In addition, the motion control of the stepper motor is relatively simple, and an open-loop control method is usually adopted, that is, the rotation angle and speed of the motor are determined according to the input pulse signal. This makes the motion control of the stirring component 4 very flexible and convenient, and the stirring frequency and amplitude can be adjusted according to actual needs to adapt to different types of powder materials and working environments.

[0029] Two sets of feed pipes 12 are fixedly connected to the top of the storage box 3. By setting the feed pipes 12, powder materials can be easily injected into the interior of the storage box 3 for temporary storage. A feed port 13 is provided on one side wall of the casing 1. The weighed powder materials can be discharged through the feed port 13. The utility model can complete the feeding, weighing and feeding of powder materials in one go, with a high degree of automation.
